Slider full width issue on first load

Hi,

Love your plugin but I noticed one small issue. The slider doesn’t pick the correct screen width on mobile devices (lower than 575px). If you open the link I sent, I have 2 sliders on it and this issue makes part of the other slide visible. The weird thing is that on resizing the screen, the issue disappears and the slider works perfect.
